   Description: 
      Abstract:
         Researchers gathered data on annual snow layers at Siple Dome, Antarctica, 
         using borehole optical stratigraphy. This data set contains annual layer 
         depths and firn optical brightness. The brightness log is a record of 
         reflectivity of the firn, and peaks in brightness are interpreted to be 
         fine-grained high-density winter snow, as part of the wind slab depth-hoar 
         couplet.
